It is a steep climb to get here from either the north or south, but easier than Rhinog Fawr from the west. Great views, and the cliffs of the west side side are a playground for rockclimbers.

Cadair Idris, on the southern edge of Eryri (Snowdonia), is a majestic mountain and a grand adventure for runners. Standing at 2,930 feet (893 m), it's a challenging ascent, but the paths are good and the views - if you're lucky enough to visit on a clear day - are spectacular. Most people will use the Pony Path from the north or the Minffordd Path from the south, both of which offer an engaging way to climb or descend the mountain. The two llyns (one on each side of the mountain) can be added into a run to create a figure of eight from either side, with amazing scenery and lots of ascent and descent. Underfoot, the trails are well-maintained but the summit is quite rocky. There's a roomy stone shelter near the summit, handy for taking a break out of the wind before tackling the descent.

The Cadair Idris is certainly not the highest mountain in Wales. Still, it was definitely worth climbing this mountain. Mountains in Wales have an ancient look to them in my opinion. The weather can be very unpredictable and changeable, which means something adventurous and mysterious. This walk is started via the pony path, between trees along a lovely stream. It opens out onto a mountainside of grass and heather while also overlooking rugged slopes. It is rocky at the top of the mountain. Also the first descent via the Fox path. You descend between mountain lakes and see the sea in the distance. Then you come to a beautiful moorland where a stream meanders through and runs between grazing sheep. You end up in a fresh green area. Tip: A good GPS is recommended. When the fog sets in, you as a tourist really do not succeed in orienting yourself on your location. And the weather can be fierce.

The northeastern high point on the Cadair Idris massif, Mynydd Moel sees a fraction of the footfall of the main Penygadair summit. However, it's a wonderful place to gaze out across the Harlech Dome towards the Rhinogs and the famous peaks of northern Snowdonia.

Stunning views of Snowdonia. A little less trodden than Yr Wyddfa in northern snowdonia. Interesting paths and landmarks. One of my favorite Summits.

Stunning summit with great views. Steep and loose under fun on the Minffordd path, but rewarded with amazing views!
